Pin out for IBM 39Y7201 Servr Power support ( Emerson unit )

[Rick]

Does anyone know the pin layout of this power supply.

I does not hav ethe normal pins it has board edge connector.

2 sets of signals ( 8 on top 8 on bottom ) and three 12V power outputs.
this is rated at 12v -- 55 amps.


If someone can explain how to check the pins to determine the meaning of them.
for example ground, 3v, 5v , other signals pins so I can limit the pins I need to try jumping.

Thanks any help would be great.  thanks
